Other relevant info you may wish to add:

• gem --version returns 3.2.28

Expected Behavior

Running gem push path_to_gem.gem should result in releasing the gem to RubyGems.org successfully.

This works in jruby-9.2.19.0

Actual Behavior

In jruby-9.3.0.0, I get a broken pipe IOError when running gem push path_to_gem.gem:

% gem push pkg/glimmer-dsl-swt-4.21.0.1.gem 
Pushing gem to https://rubygems.org...
ERROR:  While executing gem ... (IOError)
    Broken pipe

It works fine in ruby-3.0.2 and jruby-9.2.19.0. My Internet works well and the same in all cases.
